PUNCHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 369,597, dated September 6, 1887.

I Application filed April 252, 1887. Serial No. 235,804. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER GAY, a citizen of the United States, residing at Providence, in the County of Providence and State of Rhode Island, have invented a new and useful Improvement in Combination Punching,

.Uutting, and Pressing Machines, of which the following is a specification.

My invention relates to a combination punching, cutting, and pressing machine adapted especially for the use of wheelwrights and blacksmiths; and it consists in a certain novel construct-ion and arrangement of parts for service, fully set forth hereinafter, and specifically pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view thereof. Fig. 2 is a central longitudinal section of same. Fig. 3 is a top plan View. Figs. 4 and 5 are detail sections.

Referring by letter to the drawings, A designates the frame or bed of the machine, having the vertical sides B B, the side B being provided near the rear end with a bearing, 1), and side B with a slot or opening, b, and G is an integral plate on the outer side of the side B, having a bearing, 0, therein, similar to and aligned withthe bearing 12, 0 being a rem0vable portion of the said plate 0, the purpose of which will be hereinafter described.

D is a plate secured in the front end of the frame between the sides B B, having a round opening, d, therein, and G is an eccentric power-shaft, journaled in the aligned bearings I) c in the rear end of the frame, having the outer end squared and provided with a power lever or handle, B. It will be seen that by means of the removable plate 0 the said eccentricshaft may be taken out of its bearjournaled at the rear end on ings.

I is the punclrbar, sliding at the front end in the guide-opening cl, and having the bifurcated rear end in which is pivoted the front end of the connecting-rod or link K, which is the eccentric shaft G.

k k are small studs on opposite sides of the said bifurcated rear end of the punch-bar, formed by the extremities of the pivot-pin k", adapted to slide in guide-grooves la la in the inside of the sides B B.

It will be readily seen that as the handle or lever H is oscillated the punch-bar will be reciprocated forward and backward, and will approach and recede from the block or standard L, which is provided with an opening, Z, therein, directly in the path of the saidend of the punch-bar, and M M M are ears or flanges on the side of the said block toward the punchbar, provided with set-screws an, adapted to impinge against the sides of the die-block N when placed between the said ears and hold the same in place.

A recess or opening, 0, is made in the front end of the punch-bar to receive punches, cutters, or pressing-dies and be secured therein by the set-screw 0.

The bed of the machine is extended out a short distance beyond the said block or support for the dies, as seen at P, and the braces l? are secured in position to brace the said block, thus forming the receptacle to catch and retain the blanks, 820., out out by the operation of the machine.

The operation of the machine will be readily understood from the foregoing description, and it will be seen that the punch-bar is adapted to have punches, cutters, and pressing-dies readily secured therein, according as one or the other is needed or desired; also, the block is adapted to have the dies changed and rigidly secured in place by very simple means.

Thepower exerted by thepunch-barthrough the agency of the long lever-arm and the cocentric-shaft is very great, and as the means employed are simple, and consequently inexpensive, the implement is especially adapted for the use of carriage builders and blacksmiths.

It may, if desired, be disposed in a vertical position by fastening the same to a post or other vertical support.

Having now described my invention, I claim- 1. In a punching-machine, the combination of the frame A, provided with the sides B 13, having the guidegrooves k therein, the plate D at the front end of the frame, having the guide-opening d therein, eccentric power-shaft G, journaled in bearings in the sides of the frame, the punch-bar I, guided at the front end in the opening d, the studs 70 on the sides thereof, to operate in the grooves 70, and the link K, to connect the eccentric-shaft to the punch-bar, substantially as specified.

2. Thecombination, inapunching-machine, with the frame A, eccentric power-shaft G, journaled therein/the lever H, and the link K, of the punch-bar I, adapted to be reciprocated horizontally by the oscillation of the said lever, having a recess, 0, in the free end adapted toreceive any desired punch, cutter, or pressing-die, and the set-screw o, to bear at the inner end on the said cutter, punch, or pressing-die to hold the same in place, substantially as specified.

3. In a punching-machine, the combination, with the frame A, the eccentric-shaft G, jour naled therein, punch-bar I, operated thereby, and the connecting-link K between the said shaft and the punch-bar, of the block or standard L, having the opening Z therein, opposite the end of the punch-bar, ears M M M on the said block, and set-screws m in the ears M, adapted to be screwed inwardly to engage the die, which is placed between the said ears, and hold the same in position, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
